Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

Write the least common multiple of 7 and 14.

Answer 1

14

Explanation:

To work out the lowest common multiple, we first:

1. List multiples of both numbers
2. Find the first similarity

7, 14, 21, 28...

14, 28...

The common multiples of 7 and 14 are 14, 28 etc, but the LEAST (or lowest) common multiple is 14.

Hope this helps.
